La-la-la! Biology makes me so happy!
Biology? more like BYE-ology? don't worry you have come to the right place!

Clinical Obesity
overweight to a degree which causes medical complications
KEY CONCEPT:
Scientific evidence for health risks of trans fats and saturated fatty acids.
Trans fats: what do they do in the body?
Similar to saturated and animal fats, trans fats ALSO lead to clogged arteries.
Clogged arteries can be identified as symptoms of heart disease.
THIS MEANS THAT, the risk of heart attack and stroke are increased.
DON'T make Beaker's mistake...
Trans fats increase lipoportein (LDL) which has low density or "bad" cholestrol levels.
This leads to the accumulation of fatty plaque in arteries.
"The science that shows that trans fats increase LDL cholestrol leves is outstanding and very strong. All evidence is pointing in the same direction," (Lichenstein)"
The Nurse's health Study found women who took in the most trans fats in their diets, acquired a 50% greater potentiality of having a heart attack.
Blood levels are increased by trans fats of two other compounds whose arteries are clogged;
1) 1 LIPOPROTEIN- a fat protein
2) TRIGLYCERIDES- blood fats
According to population studies, trans fats could potentially increase the chance of getting diabetes.
However, Researchers from the Harvard School of Public Health in Boston, have stated that the risk of diabetes can be reduced by 40 % with the replacement of trans fat with polyunsaturated fats in teh diet. (oils, vegetable, salmon and more)
Trans fats: what do they do in the body? - the SCIENCE Behind it....
SCIENCE continued...
There are a variation of impacts, different fats have on the health of humans.
However, the main issue is named as coronary heart disease (CHD).
CHD entails the partial blockage of the coronary arteries due to fatty deposits. This eventually leads to the formation of blood clots and heart attacks.
A positive correlation exists between rates of CHD and the intake of saturated fatty acids.
Correlation ≠ causation is an example of another factor; dietry fibre could be responsible
However the Maasai of Kenya are an example of a population who don't fit nto the corrleation. This is because of the fact that their diet is plentiful in blood, milk, fat, and meat.
They consistently consume saturated fats, and as a result of this CHD is extremely rare in this community.
In addition to this community, countries around the Mediterranean are known to have diets which are plentiful in olive oil. Olive oil consists of cis monounsaturated fatty acids. As a result of this, the populations of such countires also have low vaues of CHD; this may be because of the consumption of the cis monounsaturated fatty acids.
GENETIC FACTORS in populations could be a leading cause.
OTHER SEPERATE COMPONENTS OF THE DIET could provide reasoning for the CHD rates.
Positive correlation exists between trans fat consumed and the rates of CHD.
fatty deposites have been discovered in the infected arteries of victims of CHD to consist of a high concentration of trans fats.
